This invention provides a process for irradiating steroiddienes to produce new steroid compounds.

In the process of this invention a A -3-keto-steroid of which the ring A has the formula wherein each R is hydrogen or a lower aliphatic hydrocarbon radical is subjected to irradiation.

The irradiation is preferably carried out in an organic solvent, such as an alcohol, for example, methanol, ethanol, aropanol, butanol, or an ether, for example, diethylether, dioxane, or a carboxylic acid, for example, acetic acid, propionic acid or butyric acid, in the presence or absence of Water. .As sources of light there may be used artificial or strong natural light. There is advantageously used ultra-violet light such as is produced by a high pressure mercury lamp, or strong sunlight. Usually the process is carried out at a temperature Within the range of C. to +150 C., but the reaction can be carried out at higher or loWer temperatures, as it has been found that the choice of the temperature has less influence on the course of the reaction than the choice of the solvent and/or the period of irradiation. With short periods of irradiation ketonic reaction products are preferentially formed, and long periods of irradiation result almost exclusively in phenols. The irradiation products obtained apparently contain rings A and B having the following Formulae I to XVII:

Specific starting materials are, for example, the following A -3-lteto-steroidsz l-dehydro-testosterone and esters thereof, l-dehydro-testosterones containing a lower aliphatic hydrocarbon radical, for example, a methyl, ethyl, propyl, butyl, vinyl, ethinyl, allyl, propargyl or methallyl group in the 2-, 4-, 6- or Nor-position, l-dehydro-compounds of cortisone, hydrocortisone, ll-epihydrocortisone, corticosterone, 11 dehydrocorticosterone and the corresponding or 12a-fluoro, 902- or l2a-chloroand/or c-OXY-d61lV3lIlV6S of aldosterone, cortexone, 17u-hydroxyand l8-hydroXy-cortexone, progesterone and 1102-, 11fi-hydroxy-, ll-keto-progesterone.

In the esters of the above mentioned starting materials the acyl groups are preferably those derived from lower from l-dehydro-testosterone derivatives are of special therapeutic interest owing to their high anabolic action and are useful as medicaments in treating diseases calling for medicaments having such action. The phenolic irradiation products obtained from l-dehydrosterone possess anti-androgenic activity.

The following examples illustrate the invention:

EXAMPLE 1 3 grams of l-dehydro-testosterone acetate are dissolved in 75 cc. or absolute dioxane, and the solution is irradiated in a cylindrical quartz vessel, which is provided with a cooling finger, at about 10 C. for 80 minutes by means of a high pressure quartz burner type Biosol Philips (25'0-W). The distance of the burner from the reaction vessel is about 10 centimetres. During the irradiation the solution is powerfully stirred with a magnetic stirrer. The solution is worked up by cautiously evaporating it to dryness under reduced pressure produced by a water jet pump at 2030 C., and the residue is then dried overnight in a high vacuum at room temperature. In order to separate the neutral ketonic constituents from the phenols also formed in small quantity, the crude product is dissolved in a small amount (about 15 cc.) of benzene and the solution is filtered through a column of 90 grams of neutral aluminum oxide (activity II). A total of 2.45 grams of an oil is eluted from the column by means of 4 liters of benzene, and the residual phenolic substance amounting to about 0.5 gram is extracted with methanol (about 550 cc.).

In order to split up the products eluted with benzene they are dissolved in 6 cc. of a mixture of petroleum ether and benzene (1:1) and the solution is transferred to a column of 28 millimeters diameter of 200 grams of aluminum oxide of activity III, the column having been prepared with a mixture of petroleum ether and benzene (10:1).

Ketne-B.By means of 2.8 liters of a mixture of petroleum ether and benzene, the relative proportions of these components being increased from :1 to 1:1, there are eluted 350 milligrams of crystals which melt between 145 C. and 155 C. After being recrystallized three times from a mixture of acetone and hexane (or a mixture of ether and pentane) this product melts at a constant temperature of 16l162 C., and it has the specific rotation [u] =145 C. (c.=0.70). Its ultra-violet absorption spectrum exhibits a maximum at 238 mg, log 6 3.34, and end absorption at 207 mg, log e 3.70, and absorption bands in the infra-red at 1739 (acetate), 1693 emf- 1669 cm.- 1640 cm.- and 1567 cm.-

Analysis: C H O Found C, 76.51%; Calculated C, 76.79%; H, 8.59%.

This compound is referred to as ketone-B and is probably A -4:10-cyclo-3-oxo-5-methyl-17,8-acetoxy 19 nor testene or A -1:5-cyclo-2-oxo 17B-acetoxy-testene of the Upon hydrogenation with palladium charcoal (5%) in rectified spirit this ketone yields after the absorption of 1 mol of hydrogen dihydro-ketone-B melting at 164-165' C.

after recrystallization from a mixture of acetone and hexane, and having the specific rotation [a] =+37 (c.=0.8l). This compound exhibits in the ultra-violet absorption spectrum merely an end absorption at 212 mu, log 6 3.78. In the infra-red absorption spectrum it exhibits bands at 1730 cm.- (acetate) and 1712 cm? (G-ring-ketone). The probable formula of dihydrO- ketone-B (4:l0-cyclo-3-oxo-5-methyl-l7 3-acetoxy-19-nor testane or l:5-cyclo-2-oxo-17,8-acetoxy-testane) is Analysis: C H O -F0und C, H, 9.12%. Calculated C, 76.32%; H, 9.15%.

Ket0ne-C.260 milligrams of crystals of crude material melting at l15l45 C. are then eluted with 800 cc. of a mixture of petroleum ether and benzene (1:1). After recrystallizing the crude product 4 times from a mixture of acetone and hexane (or a mixture of ether and pentane) its melting pointrises to l61162 C. Melting point tests upon a mixture of the latter product with ketone-B gave a depression of 45 C. It has the specific rotation [a] e=-l41 (c.=0.54). It exhibits in the ultra-violet absorption spectrum a maximum at 242 mu, log 6 3.8, and the end absorption is at 207 m log 6 3.70. In the infra-red absorption spectrum it exhibits bands at 1738 cm? (acetate), 1693 and 1576 cm." =chromophore system.

Analysis: C H O Found C, 77.13%; H, 8.68%. Calculated C, 76.79%; H, 8.59%.

By catalytic hydrogenation of the ketone-C with palladium charcoal (5%) in rectified spirit a dihydro-derivative is obtained melting at 166168 C. (after recrystallization from a mixture of acetone and hexane), which is apparently identical with clihydro-ketone-B.

According to mixed melting point tests and infra-red spectrum analysis ketone-C is different from ketone-B. When the depression occurring in the mixed melting point tests of the two dihydro-ketones-B and -C is not considered sufficient ketone-C must have a structure containing an cup-unsaturated CO-group and a 3-membered ring according to the formulae of) U N -1:19-cyc1o-17B-acetoxy- 3-keto-testene A -2: lo-cyclo-l-m ethyl-19- nor-17fi-acet0xy-3-keto-testene (probable) Ket0ne-D.-147 milligrams of an oil which up to now does not crystallize are eluted with 800 cc. of a mixture of petroleum ether and benzene (1:1). By similar tests carried out separately it is possible to obtain from this portion of the chromatogram crystalline ketone-D which melts at 174-175 C. after recrystallization from a mixture of acetone and hexane and has the specific rotation [x] =-\-296 (c.=0.45). In the ultra-violet absorption spectrum ketone-D exhibits bands at 270 my, log e 3.56; 226 m log e 3.81, and end absorption at 208 my, log 6 4.08.

After recrystallizing the product four times from a mixture of acetone and hexane its melting point rises to 157-15 8 C. and it has the specific rotation [e] =15 (c.=0.65). Its ultra-violet absorption spectrum exhibits a band at 246 m log 5 4.26. Its infra-red absorption spectrum exhibits bands at 1731 cm?

Ketone-E probably has one of the two formulae l-dehydro-Q :10 -testosl7B-acetoxy-2-keto-testadiene terone acetate In view of the fact that decomposition with ozone leads to a ring-B ketone the first of the above formulae appears to be the more probable.

By further elution with benzene only the starting material subjectedd to irradiation, namely A -testosterone acetate, is obtained.
